A comparison for teams deciding between APISIX as an open-source gateway runtime and WSO2 as a broader API management platform.
Use this page as a decision guide, not a universal ranking. Validate any recommendation with a proof of concept that uses your own routes, policies, identity providers, logs, and deployment workflow.
Evaluation criteria
The right gateway depends on runtime behavior, operational model, extensibility, and how much of the stack your team wants to own.
Start with what runs in the request path. A gateway runtime, API management suite, ingress controller, service mesh proxy, and reverse proxy have different jobs.
For an Apache project website, the most important question is what a team can evaluate, deploy, modify, and operate from open source.
Compare how each option fits Kubernetes, identity providers, observability, CI/CD, GitOps, and cloud networking.
Comparison matrix
This matrix summarizes practical differences using official documentation and publicly available project pages.
| Criterion | Apache APISIX | WSO2 API Manager |
|---|---|---|
| Best-fit use case | Open-source API gateway runtime for dynamic routing, plugin-based policy, observability, Kubernetes workflows, and APISIX AI Gateway capabilities. | teams evaluating full API design, publishing, developer portal, policy, rate limiting, deployment, and lifecycle management workflows |
| Operating model | APISIX uses dynamic configuration and open-source gateway primitives that platform teams can self-host, extend, and operate. | WSO2 API Manager documentation covers API design, gateway deployment, developer portal, policies, security, and lifecycle features. |
| Cloud-native fit | Apache APISIX Ingress Controller provides the Kubernetes controller path for APISIX; APISIX Gateway itself can also be evaluated for hybrid and self-managed deployments. | WSO2 has deployment documentation for Kubernetes and multiple runtime patterns; compare operational complexity during evaluation. |
| Extensibility | APISIX has a plugin hub spanning authentication, security, traffic control, observability, transformation, protocols, and APISIX AI Gateway use cases. | WSO2 should be evaluated as a broad API management platform, not only as a gateway runtime. |
| Open-source evaluation | APISIX is an Apache Software Foundation project licensed under Apache 2.0, with public code, issues, and contribution paths. | Evaluate the open-source boundary of WSO2, including which features, policies, and operational workflows are available in the model you plan to run. |
| Decision lens | Choose APISIX when open-source gateway control, plugin breadth, Kubernetes controller workflows, and APISIX AI Gateway capabilities are primary requirements. | WSO2 can fit when open-source API management breadth is central; APISIX can fit when gateway runtime control and plugin-driven traffic policy are central. |
Decision guide
Start with use case fit, then test the highest-risk policies and rollout path before committing to a production change.
You need an Apache 2.0 open-source API gateway with dynamic routing, a broad plugin hub, Apache APISIX Ingress Controller, and APISIX AI Gateway capabilities.
WSO2 can fit when open-source API management breadth is central; APISIX can fit when gateway runtime control and plugin-driven traffic policy are central.
Open-source next steps
Move from evaluation to hands-on testing with documentation, plugins, Kubernetes resources, GitHub, and community channels.

FAQ
It can cover many gateway runtime requirements, but it should not be treated as a drop-in replacement for every WSO2 workflow. Map routes, policies, auth, observability, deployment, and team operations before changing production traffic.
Choose APISIX when open-source gateway control, plugin-based policy, dynamic routing, Apache APISIX Ingress Controller, and APISIX AI Gateway capabilities are core requirements.
WSO2 can fit when open-source API management breadth is central; APISIX can fit when gateway runtime control and plugin-driven traffic policy are central.
